Physical exercise and anxiety as moderators of the stress-illness relationship

This study examines the interplay of unemployment stress, trait anxiety and physical exercise in the development of physical health. Longitudinal data were taken from a sample of East German migrants (N = 330) who were confronted with the potentially stressful demand of finding a job in the Western society. Unemployment stress was found to exert a main effect on illness level. Trait anxiety was a moderator of the stress-illness relationship, but exercise was not. As indicated by a three-way interaction involving exercise, anxiety, and stress, exercise was most beneficial among high-anxious subjects who were not exposed to unemployment stress. Results of this study suggest that exercise may not buffer the deleterious effects of stressful situational conditions (unemployment), but may effectively mitigate the health-damaging consequences of lacking personal resources, such as high dispositional anxiety.     

Reinforcement of wheel running in BALB/c mice: role of motor activity and endogenous opioids

The authors investigated the effect of the opioid antagonist naloxone on wheel-running behavior in Balb/c mice. Naloxone delayed the acquisition of wheel-running behavior, but did not reduce the expression of this behavior once acquired. Delayed acquisition was not likely a result of reduced locomotor activity, as naloxone-treated mice did not exhibit reduced wheel running after the behavior was acquired, and they performed normally on the rotarod test. However, naloxone-blocked conditioned place preference for a novel compartment paired previously with wheel running, suggesting that naloxone may delay wheel-running acquisition by blocking the rewarding or reinforcing effects of the behavior. These results suggest that the endogenous opioid system mediates the initial reinforcing effects of wheel running that are important in acquisition of the behavior.     

Development,Acceptability, and Effectiveness of an Acceptance-Based Behavioral Stress/Anxiety Management Workshop for University Students

College is a critical time in which individuals experience transition and stress, and may experience subthreshold or clinical symptoms of anxiety and depression. In addition, educational contexts offer a unique opportunity to serve the needs of a diverse group of students who may experience additional stressors related to experiences with discrimination; acculturative stress; financial strain; and balancing family, work, and school demands. Therefore, college appears to be an ideal time for students to learn about evidence-based skills to use in response to anxiety and depression.However, there are multiple barriers that may make it less likely that evidence-based skills and services are available to or utilized by students, including lack of funding and services available on campus, as well as concerns about mental health stigma. This study examines the preliminary acceptability and effectiveness of an acceptance-based behavioral stress/anxiety management workshop for university students on a diverse urban campus. Results indicate that participants found the workshop to be acceptable and helpful. Mixed-effect regression models examining symptom and impairment measures at preworkshop, 1-week follow-up, and 4-week follow-up showed a significant effect for time on anxious arousal, general anxiety symptoms, and social anxiety, but no significant effect for time on impairment. Implications and future directions for mindfulness and acceptance-based approaches in educational contexts are discussed.     

Anxiety and heart rate under psychological stress: The effects of exercise-training

Abstract The effects of a 12-week exercise-training program on cognitive, somatic, and behavioral anxiety and on heart rate responses to evaluative stress were scrutinized in 89 subjects randomly assigned to an experimental (exercise) or a control group. The training program consisted of exercises that were aimed to the improvement of the general physical fitness (i.e., strength, flexibility, and endurance). Following the 12-week training period, exercising subjects showed improved motor skill capacity as well as higher VO(2) max. In an anxiety inciting test situation, that consisted of the video-taped delivery of a 5-min speech, a mental arithmetic and a fine motor task, exercising subjects showed more favourable responses than control subjects in three ways: (a) they exhibited lower behavioral anxiety during the anticipation phase of the three stressors, (b) they reported lower cognitive and somatic anxiety during the anxiety provoking situation, and (c) their heart rate recovered faster, in contrast to both their baseline heart rate and the control subjects' heart rate, from the stress episode. These results demonstrate that a fitness-oriented exercise program has anxiolytic properties. They also provide a primary evidence that overt behavioral anxiety, as opposed to the usually measured self-reported anxiety, may be affected by exercise.     

The Affective Consequences of Minority Stress Among Bisexual,Pansexual, and Queer (Bi+) Adults: A Daily Diary Study

Bisexual, pansexual, and queer (bi+) individuals are at increased risk for depression and anxiety. These disparities are hypothesized to be due to the unique, minority-specific stressors that they experience. Prior research supports that bi+ stressors are associated with depression and anxiety, but nearly all studies have been cross-sectional, limiting our understanding of how experiencing bi+ stress influences individuals’ levels of depression and anxiety as they occur in their day-to-day lives. To address this gap, we examined the daily associations between bi+ stressors (discrimination, internalized stigma, rejection sensitivity, and identity concealment) and depressed/anxious mood in a 28-day diary study. Participants were 208 bi+ individuals who completed daily measures of bi+ stressors and depressed/anxious mood. We tested unlagged (same-day) and lagged (next-day) associations, and we also tested whether internalized stigma, rejection sensitivity, and identity concealment functioned as mechanisms underlying the daily associations between discrimination and depressed/anxious mood. Participants reported higher depressed/anxious mood on days when they reported higher discrimination, internalized stigma, rejection sensitivity, and identity concealment. There were significant unlagged indirect effects of discrimination on depressed and anxious mood via internalized stigma and rejection sensitivity, and there was also a significant unlagged indirect effect of discrimination on anxiety via identity concealment. However, none of the lagged associations were significant. Results suggest that bi+ stress is related to same-day, but not next-day, depressed/anxious mood. The nonsignificant lagged associations could reflect that bi+ individuals are using adaptive coping skills in response to bi+ stress, or that other experiences throughout the day have stronger influences on next-day mood.     

Does the level of physical exercise affect physiological and psychological responses to psychosocial stress in women?

ObjectivesTo test the Cross-Stressor Adaptation hypothesis for females by examining whether physically exercising young women show reduced physiological and psychological stress responses to a psychosocial stressor.DesignForty-seven healthy young women with different levels of physical exercise (17 not or rarely exercising, 15 moderately exercising, 15 vigorously exercising) underwent the Trier Social Stress Test for Groups (TSST-G); physiological and psychological stress responses during and after stress induction were compared.MethodANOVAs with repeated measures were used to compare stress reactivity and recovery between the three exercise groups. Heart rate and salivary free cortisol were used as indicators of physiological stress response, state anxiety, mood, and calmness as indicators of psychological stress response. For physiological stress reactivity, the areas under the curve with respect to the ground (AUC_G) were compared.ResultsIn all three exercise groups, experimentally induced stress led to a significant rise in heart rate, cortisol, and state anxiety; mood and calmness significantly decreased. As hypothesized, the pattern of the physiological stress response differed for the three exercise groups, with lowered reactivity in the more active groups. However, the psychological stress response partly went in the opposite direction: Exercising participants reported a higher mood decrease, suggesting a dissociation of the physiological and psychological stress responses.ConclusionsThe findings suggest that the Cross-Stressor Adaptation hypothesis is also valid for young women; however, only with regard to physiological stress response. The unexpected findings for psychological stress response need to be further explored in experimental studies.     

Clustered Patterns of Behavioral and Health-Related Variables Among Young Lesbian Women

Lesbian women are at increased risk for a variety of mental and physical health problems compared to heterosexual women. In order to inform treatment and prevention, the purpose of this study was to examine behavioral and health-related patterns among lesbian women and elucidate how these patterns are associated with general discrimination, sexual minority stress, affect, and social support. A sample of self-identified lesbian women (N = 436) completed an online survey from August 2014–March 2015. A latent profile analysis was conducted using measures of body mass index, hazardous alcohol use, binge eating, eating disorder risk, and exercise as indicators. A 5-class solution best fit the data and included two healthy groups: (a) low health risk, moderate exercise (54%), (b) low health risk + high exercise (22%); and three unhealthy risk groups: (c) obese + binge eating (14%); (d) disordered eating + hazardous alcohol use (5%); (e) disordered eating + high exercise (5%). The three unhealthy classes generally reported more general discrimination, sexual minority stress, social anxiety, negative affect, and lower social support compared to the healthy classes. These findings show that behavioral and health-related variables cluster together in several distinct patterns among lesbian women. In addition, general discrimination and sexual minority stress and associated psychosocial functioning may be related to these maladaptive behavioral and health-related patterns and may be important to consider in behavioral interventions.     

Comparison of water- and land-based exercise in the reduction of state anxiety among older adults

This study examined the effect of an acute exercise program of different exercise conditions on state anxiety among older adults. 73 healthy subjects were recruited and randomly assigned to either water exercise group (n = 36) or land exercise group (n = 37). State anxiety was assessed before exercise and following exercise. Subjects in the water exercise performed a 70-min. exercise program consisting of a 10-min. warm-up, a 20-min. brisk walking, a 20-min. rhythmic dancing, a 10-min. resistance training, and a 10-min. cool down exercise. The land exercise program contained a 10-min. warm up and a 30-min. combined endurance and resistance exercise, followed by a 10-min. cool down exercise. Analysis showed that both exercise groups scored significantly (p<.001) lower on anxiety after exercise, but there was no significant interaction for group by trial for scores on state anxiety. The data indicate that elderly persons who participate in these types of exercise report lower state anxiety.

Life events, fitness, hardiness, and health: a simultaneous analysis of proposed stress-resistance effects

The effects of exercise participation, self-perceived fitness level, and dispositional hardiness for promoting stress resistance were examined in a sample of 373 college students. Self-report measures of stressful life experience and recent physical illness were positively correlated, and fitness and hardiness were negatively correlated with illness as expected. Multiple regression analyses indicated that neither fitness nor hardiness provided a stress-moderator effect because neither was found to significantly interact with stress in the prediction of illness scores. Structural equation analyses suggested that hardiness may affect health indirectly by first influencing either the occurrence or subjective interpretation of stressful life events. No direct effect on health was found for exercise participation, although exercise may reduce illness indirectly by improving fitness. Implications for the multivariate modeling of proposed stress-resistance-enhancing effects are discussed.     

The influence of brief episodes of aerobic exercise activity,soothing music-nature scenes condition,and suggestion on coping with test-taking anxiety

This study examines the influence of aerobic exercise activity, soothing musicnature scenes condition, and suggestion on coping with test-taking anxiety. Sixty test anxious subjects were randomly assigned to four treatment groups consisting of 15-min episodes of exercise or soothing music-nature scenes condition with or without verbal suggestion that the treatment task in which they were engaged would be helpful to them. A videotaped intelligence test used to stimulate test-taking anxiety was given to the subjects after the soothing music-nature scenes condition or exercise tasks. The Multiple Affect Adjective Checklist (MAACL) was used to appraise anxiety during the laboratory procedures. Results indicate that exercise, soothing music-nature scenes condition, and suggestion play a role in reducing anxiety. While relaxation activity proved to be superior to exercise in reducing anxiety immediately following the treatment episode, these differences disappear following exposure to a stressful IQ test and exercise (as well as suggestion) had a better stress inoculation effect than soothing music-nature scenes condition or no suggestion.     

Moderate Aerobic Exercise, T'ai Chi, and Social Problem-Solving Ability in Relation to Psychological Stress

This study evaluated the importance of exercise mode, social problem-solving ability, gender, and age in relation to anxiety and perceived daily hassles. Adult participants were classified as moderate aerobic exercisers, T'ai Chi exercisers, or sedentary via completion of a questionnaire. Social problem-solving ability, state and trait anxiety, and frequency and severity of daily hassles were measured. As predicted, scores indicating effective social problem-solving ability were associated with fewer reported severe daily hassles and with lower scores on state and trait anxiety. For state and trait anxiety, a main effect of exercise mode emerged after age and gender were controlled. A 3-way interaction involving age, gender, and exercise mode suggested that age and gender moderate the effects of exercise on anxiety, that is, the stress-reducing efficacy of different exercise modes may be dependent on a person's age and/or gender. Implications for theory, research, and practice are discussed.     

When Adolescents Experience Co-Occurring Social Anxiety and ADHD Symptoms: Links With Social Skills When Interacting With Unfamiliar Peer Confederates

Adolescents with elevated social anxiety commonly experience peer-related impairments – particularly with same-age, unfamiliar peers – stemming from their avoidant behaviors. Yet, peer-related impairments are not unique to social anxiety. For example, adolescents who experience social anxiety may also experience symptoms of attention deficit/hyperactivity disorder (ADHD), which also increase risk for peer-related impairments. Relative to social anxiety, peer-related impairments linked to ADHD symptoms more likely stem from hyperactivity (i.e., approach behaviors). These distinct pathways point to adolescents with elevated social anxiety and ADHD symptoms (i.e., social anxiety + ADHD) experiencing particularly high peer-related impairments, which commonly manifest as behavioral displays of low social skills when interacting with unfamiliar peers. We tested this notion in a mixed-clinical/community sample of 134 14- to 15-year-old adolescents and their parents. Adolescents participated in a series of social interaction tasks designed to simulate how adolescents interact with same-age, unfamiliar peers. Trained observers independently rated adolescents on observed social skills within these interactions. Both parents and adolescents completed parallel surveys of social anxiety and ADHD symptoms, which we used to identify social anxiety + ADHD adolescents as well as other combinations of social anxiety and ADHD symptoms (i.e., neither, elevated on one but not the other). Adolescents with social anxiety + ADHD displayed significantly lower social skills, relative to all other groups. Among adolescents, social anxiety + ADHD may have a compounding effect on social skills. As such, therapists working with social anxiety + ADHD adolescents should probe for peer-related impairments and factors implicated in the development and maintenance of these impairments.     

A preliminary study of the moderating role of church-based social support in the relationship between racist experiences and general anxiety symptoms

The current study explores the potential buffering effect of church-based social support on the effect of racism on anxiety symptomology in a Black sample. Fifty participants completed a questionnaire packet containing measures of anxious arousal and stress (general anxiety) symptoms, church-based social support, and experience of racist events. Results indicated that church-based social support moderated the relationship between racist experiences and general anxiety symptoms such that at low levels of church-based social support the experiences of racism and stress (general anxiety) symptoms were significantly positively associated. The clinical implications of these findings and future research directions are discussed.     

Performance on creativity measures with examination‐taking instructions intended to induce high or low levels of test anxiety

The major purpose of this investigation was to ascertain whether differential levels of performance on three tests of creativity portraying divergent production of verbal (semantic), figural (visual), and mathematical (symbolic) responses would be associated with two sets of test‐taking instructions: (a) one intended to induce a relatively high level of anxiety or stress and (b) the other designed to minimize the degree of anxiety or stress in the testing experience. Participants were 132 private secondary school students (82 females and 50 males) in a college preparatory program who were divided into experimental and control groups. On the basis of three univariate four‐way factorial designs at each of two levels per variable (treatment x sex x test anxiety x mathematics anxiety) with the pretest serving as a covariate, it was observed that only in the instance of a mathematics fluency test did the experimental group exposed to anxiety‐inducing test‐taking instructions achieve a significantly lower mean score on the posttest than did the control group that had been administered instructions intended to minimize anxiety (p < .001). A marginally significant interaction occurred between gender and mathematics anxiety on the mathematics fluency test with highly‐anxious males showing a greater decrement in performance than highly‐anxious females when exposed to anxiety‐inducing instructions. The results were interpreted primarily within a conceptual framework developed by Tobias (1985), who proposed an integration of cognitive capacity and interference as explanatory constructs for decrements in the performance of tasks involving anxiety.     

The effects of physical exercise on psychophysiological reactions under stress

Abstract

The effects of moderate physical exercise during a 20-minute anticipation period of a public speech were investigated. Mood before the anticipation period was manipulated as an additional stress factor. As a third experimental factor the subjects were given the opportunity for task preparation or not. Besides cardiovascular variables and self-reports of bodily symptoms, mood reports served as dependent variables and as indicators of general well-being. Eighty female students took part in the study. Moderate exercise was associated with strongly increased activation and reports of related bodily symptoms. The reported mood changes as a function of exercise included a decrease in anxiety and an increase in self-reliance. This mood repair effect of exercise was especially apparent when the subjects entered the anticipation period in a negative emotional state. The exercised subjects spoke with greater calmness. The task preparation during anticipation led to slightly increased activation and to reports of bodily symptoms as well as increased anxiety and less self-reliance. The prepared subjects made fewer pauses in their speeches.     

The Correspondence Between Attachment Dimensions and Prayer in College Students

Attachment theory applied to religious behavior suggests that at a given point in time, "avoidant" individuals (who experience discomfort with closeness) engage in less prayer overall, and less prayer during times of stress than nonavoidant individuals. Additionally, "anxious" individuals (who worry about abandonment) would be expected to engage in more help-seeking prayer than nonanxious individuals. To test these hypotheses in a college sample, the frequency of three types of prayer were individually regressed on avoidance, anxiety, anxiety × avoidance, stress, stress × avoidance, stress × anxiety, in addition to the control variables of age, church attendance during childhood and adolescence, gender, gender × avoidance, and gender × anxiety. The hypotheses were supported in so far as: (a) avoidance was significantly and negatively related to colloquial (conversational) and meditative (contemplative) prayer, (b) stress × avoidance showed the predicted relation to colloquial and meditative prayer, and (c) anxiety was a significant predictor of petitionary (materialistic help-seeking) prayer, only.     

Reinforcement value and substitutability of sucrose and wheel running: implications for activity anorexia

Choice between sucrose and wheel-running reinforcement was assessed in two experiments. In the first experiment, ten male Wistar rats were exposed to concurrent VI 30 s VI 30 s schedules of wheel-running and sucrose reinforcement. Sucrose concentration varied across concentrations of 2.5, 7.5, and 12.5%. As concentration increased, more behavior was allocated to sucrose and more reinforcements were obtained from that alternative. Allocation of behavior to wheel running decreased, but obtained wheel-running reinforcement did not change. Overall, the results suggested that food-deprived rats were sensitive to qualitative changes in food supply (sucrose concentration) while continuing to defend a level of physical activity (wheel running). In the second study, 15 female Long Evans rats were exposed to concurrent variable ratio schedules of sucrose and wheel-running, wheel-running and wheel-running, and sucrose and sucrose reinforcement. For each pair of reinforcers, substitutability was assessed by the effect of income-compensated price changes on consumption of the two reinforcers. Results showed that, as expected, sucrose substituted for sucrose and wheel running substituted for wheel running. Wheel running, however, did not substitute for sucrose; but sucrose partially substituted for wheel running. We address the implications of the interrelationships of sucrose and wheel running for an understanding of activity anorexia.     

特质正念与大学生焦虑和攻击性的纵向关系：心理弹性的中介和留守经历的调节

基于心理弹性的整合模型和压力与健康关系的终生发展模型,以629名大学生为被试,进行间隔时间为三个月的两次施测,探讨特质正念与大学生焦虑和攻击性的关系及其作用机制。研究发现:(1)特质正念对大学生焦虑和攻击性具有显著的负向预测作用;(2)特质正念通过心理弹性的中介作用预测大学生焦虑和攻击性;(3)留守经历调节了特质正念→心理弹性→焦虑/攻击性的后半段,具体来说,相对于有留守经历的大学生而言,无留守经历大学生心理弹性对焦虑和攻击性的保护作用更为显著。研究结果强调了特质正念和心理弹性是大学生内外化问题的保护因素,而童年期的留守经历是成年后个体心理资源和内外化问题的风险因素,这对大学生内外化问题的干预具有重要的参考价值。     

Fear of fear,trait anxiety and aerobic fitness in relation to state anxiety during adrenalin provocation

Abstract

Psychological explanations of both spontaneous and experimentally induced panic anxiety stress the role of fear of fear, especially fear of bodily symptoms of arousal. Fear of fear is conceptually different from trait anxiety but may be associated with repeated experience of arousal symptoms in fearful situations, while frequent physical exercise may lead to habituation to these symptoms. To test this hypothesis, 44 healthy male volunteers, classified as having high or low trait anxiety and high or low aerobic fitness, underwent a single-dose adrenalin infusion (80 nanogram/kilogram bodyweight/minute). In both groups, during the experiment a significant rise in state anxiety was found; compared to the group with low trait anxiety, subjects with high trait anxiety reported higher levels of state anxiety, which could be attributed to differences in aerobic fitness. In the high-anxious group, subjects showed a greater decrease in state anxiety during the recovery phase. State anxiety during adrenalin was strongly associated with fear of bodily symptoms only in the high-anxious group. Correlations between trait anxiety and somatic anxiety were not significant; state anxiety scores tended to correlate negatively with physical fitness. It is concluded that these results lend support to a fear of fear-model of panic anxiety.
